a mid terrace has less than 20% outside walls compared to a normal house off around 45% plus around 10 to 15% off heat generated and hitting the connecting walls each side will transfer through the walls iff they are on around 22 degrees and you are on 12 degrees
a typical set up is front wall off the house 14ft wide external front room 13ft deep so front room up and down 73% internal
halway and stairs fully internal
back rooms up and down 1/2 a wall external so 13% external
typical kitchen and back room up stairs 50% external
as said above solar gain plus any excess heat from any electrical gadgets not venting outside
a person will give out up to a kw off heat
any way all that aside i live in a mid terrace my heating has so far this winter been on for less than 10 hours total the temperature has not dropped below 18 degrees in the main room when it does i turn the heating on for 30 mins
there is little solar gain in my house e.s.east facing other rooms in the house are cooler

hmmm, mid terrace here and without heating it is never below 19 degrees.
Have to admit fully insulated walls and ceilings.
Sun , when out on front all day.

Don't forget Joe, your computer kicks some heat out, plus the fridge/freezer. Plus, it always seems warmer if your inside out of the wind (the chill factor comes into effect) All these factors come into consideration, plus all the visitors you undoubtedly have. Their body heat adds to the heat inside your abode.

Joe, if you have more than one username, would that mean you emit more heat than just a single person?
outside air temperature in bright sunlight say 25-30 degrees in direct sunlight say 40 to 45 degrees temperature 22 degrees so half the outside temperature
outside temperature say o-10 degrees inside say 15 degrees so double the outside temperature

'cos its where they dumped all the spent fuel from Sellafield.
I went into a Nissan Hut once - they make cars too , according to the owner.
You do know the Sun and the Moon are the same thing don't you? And there's more than one? The Suns are switched on and hot in the day then at night are turned off and so go cold, we call them Moons. They then get switched back on in the morning. Possibly someone left the Sun over Joe's house turned on. There are many reasons it could be warm in your house Joe, but that's the most obvious. Check it out.
